Essential Fish Habitat GIS Shapefiles

GIS shapefiles of Essential Fish Habitat (EFH) boundaries for Atlantic Highly Migratory Species are available for download by clicking the associated button below. Species that have EFH boundaries for multiple lifestages (i.e., anything besides "all lifestages combined") also contain layer files for each lifestage polygon. The symbology used in the layer files (e.g., colors) are random, and you will need to update the location of the shapefiles that you download for the layer files to reference the appropriate data.
